COOLING DEVIGE Specification of Letters Patent. Application filed November 10,1904. Serial No. 232,205-- FOR ENGINE-CYLINDERS.-

To all whom it may concern:

Be it known that I, Lnw s D. ZENT, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements i -Cooling Devices for Engine-Cylinders; and I do declare the following to be a full, clear, and exact description of the invention, such skilled in the art to which it appertains to make and use the same. 1

My invention relates to heat-radiating devices, and more particularly to such devices for cooling or radiating the heat generated in the cylinders of gas or explosive engines. The object of my invention is to provide a simple and highly-efficient coolin means of this character which may be app ied to the cylinder or any other part of a motor at comparatively low cost.

With the above and other objects in View Y the invention consists of certain novel features of construction, combination, and arrangement of devices hereinafter described and claimed. v 1

In the accompanyingdrawings, Figure 1 is a vertical transverse sectional'view throu h a portion of an engine-cylinder, showing the application of my invention thereto. Fi 2 is a vertical longitudinal sectional view ta en.

on the line 2 2 of Fig. 1, and Fig. 3 is a plan view of a'portion of one of the heat-radiating strips before the same has been secured upon the engine-cylinder.

Referring to the drawings by numeral, 1 denotes a ortion of a metal object from which it is desired to radiate heat and which in the present instance is a portion of an engine or motor cylinder, and 2 denotes my iniproved heat-radiating devices, which are in the form of strips of woven-wire fabric. Said strips 2 may be of any suitable form and construction, and they ma be arranged in any desired manner u on t e cylinder 1; but I preferably have t em extend longitudinally and radially and arrange themin pairs, as shown. Each of said pairs is fastened in a longitudinally-extending groove 3 ,.which is formed in the outer surface or peri hery of the cylinder 1. This fastening is e ected by inserting within said groove between the as will enable others strips a calk or strip 4 of soft metal, preferably copper, and then ex anding this fastening-stri to cause it to fil the spaces between the en s of the wires which extend into said grooveand hold said heat-radiating strip securely in the groove. Before inserting the woven-wire-fabric strip in the groove 1 referably flatten, as shown at 5 in Fig. 3 o the drawings, thev ends of the wires of said strips, which are to project into said groove in order to permit them to firmly engage the walls thereof. Since the fastening-strips 4 are of -much softer metal than the engine-cylinder 1, they will expand to a reater extent than said cylinder, so that the fastening-strips will be firmly'secured in the groove of the cylinder at all times. If desired, the walls of the groove 3 may be slightly under cut in order to permit the fastening-strips to wedge the flat: tened ends of thewires of the strips 2 apart, and thus provide a better connection; but this is not necessary when the fasteningstrips are of softer metal than the enginecylinder.

The use, my invention will .be readily understood from the fore oing description, taken in connection wit 'the accompanying drawings. It will be seen that these heat-radiating strips of woven-wire fabric maybe quickly and easily secured in the grooves of the enginecylinder at a comparatively small cost and that they will effectively radiate the heat generated within the cylinder. While I have shown and described my invention as applied to the cylinder of an engine, it will be understood that the same may be similarly ap Patented May 8, 1906..

construction, and advantages of resorted to without departing from the principle or sacrificing any of this invention.

Having thus described'my invention, what I claim as new, and desire to secure by Letters Patent, is In a device of the character described, the combination of a cylinder havin a series of ooves formed therein, pairs of eat-radiating strips of reticulated material having their the advantages of inner edges flattened and bearing against the In testimony whereof I have hereunto set Walls of said groove, and a fastening-strip inmy hand in presence of two subscribing Wit- Io serted in each groove between the'fiattened nesses.
